碳基燃料SOFC阳极材料研究进展

Recent anode advances in solid oxide fuel cells with carbon-based fuels

固体氧化物燃料电池(SOFCs)是一类可以将燃料气体的化学能以高效而环境友好的方式直接转化为电能的电化学反应器。最近的研究趋势是发展可以直接电化学氧化碳氢化合物燃料(如天然气)的电池,但是使用碳氢化合物作为燃料时,目前最常使用的镍-氧化钇稳定的氧化锆(Ni/YSZ)金属陶瓷阳极材料具有易积碳和硫中毒的缺点。因此,研究在燃料气氛下具有混合离子-电子电导的替代阳极材料显得尤为必要。综述了以碳基燃料工作的SOFCs阳极材料研究的一些进展,并展望本领域在未来的发展趋势。

Solid oxide fuel cells （SOFCs） are electrochemical reactors that can directly convert the chemi- cal energy of a fuel gas into electrical energy with high efficiency and in an environment-friendly way. The recent trends in the research of solid oxide fuel cells concern the use of available hydrocarbon fuels, such as nature gas. The most commonly used anode material Ni/YSZ cermet exhibits some disadvantages when hydrocarbons were used as fuels. Thus it is necessary to develop alternative anode materials which show a mixed conductivity under fuel conditions. This article reviews the recent developments of anode materials for SOFCs with carbon-based fu- els. The future trend in this field is briefly summarized as well.
